BAT42W-G3-18

Single Diodes Overview

The BAT42W-G3-18 is a general-purpose Schottky barrier rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a metal-to-silicon construction designed for low turn-on voltage and fast switching applications. The device is housed in the SOD-123 surface-mount package, suitable for automated assembly processes. Key electrical specifications include a maximum repetitive peak reverse voltage of 30 V and an average forward rectified current rating of 200 mA. The component exhibits a typical forward voltage drop of 1 V at 200 mA and a maximum reverse leakage current of 500 nA at 25 V. It operates within a junction temperature range up to 150°C.

Single Diodes Feature Summary

• Low forward voltage drop for improved efficiency
• Fast switching capability with minimal reverse recovery time
• Integrated protection against excessive voltage such as electrostatic discharge

Single Diodes Applications

• High-frequency rectification in power supplies
• Clamping and protection circuits
• DC-DC converter output rectification

Single Diodes Procurement Notes

Verify the specific suffix G3-18 to confirm RoHS compliance and packaging type. Ensure the ordering code matches the required SOD-123 tape-and-reel quantity. Cross-reference the manufacturer datasheet for any recent product change notifications or lifecycle status updates before finalizing procurement plans.

Single Diodes Selection Notes

Select this component when a small signal Schottky diode with 30 V blocking capability is required in a compact surface-mount footprint. Compare the 200 mA current rating against circuit load requirements. Consider the thermal performance and package size relative to alternative packages like DO-35 if higher current handling is needed.

Single Diodes Part Context

This part belongs to the BAT42 series of general-purpose Schottky diodes from Vishay. The series is characterized by its metal-to-silicon technology, offering superior performance over standard silicon rectifiers in terms of speed and forward voltage. The W suffix typically denotes the SOD-123 package variant within this product line.

Single Diodes Replacement Considerations

Direct substitutes may include other 30V 200mA Schottky diodes in SOD-123 packages from different manufacturers. Verify pinout compatibility and ensure equivalent electrical parameters such as reverse leakage and forward voltage are met for the specific application environment.
